Overview
The LILYGO T-Mini E-Paper S3 is a miniature development board based on the ESP32-S3FN4R2 dual-core LX7 processor. Its defining feature is a tiny 1.02-inch e-paper display (128×80 pixels, GDGDEWG102T4 driver) that delivers ultra-low-power status and text output in a very small form factor. The board integrates 2.4GHz WiFi and Bluetooth 5 LE for wireless connectivity, 4MB flash, 2MB PSRAM, and a TF card slot for expanded storage. An 18350 Li-Ion battery (not included) can be connected for portable operation. Two frequency variants are offered (868MHz and 915MHz), hinting at optional LoRa radio integration. Compatible with Arduino IDE and PlatformIO.
